Drinkable Dairy Probiotics

Probiotic drinks are beverages containing live and active bacteria scientifically studied for their effects on intestinal flora health. When consumed regularly, these live bacteria may contribute to a healthy balance of intestinal flora and overall well-being. Bio-K+ Dairy Drinkable Probiotics are produced through a unique co-fermentation process: three proprietary strains — L. acidophilus CL1285®, L. casei LBC80R®, and L. rhamnosus CLR2® — are fermented together in a dairy base, creating a synergistic formula that delivers 50 billion live and active bacteria per bottle, guaranteed until the best before date.

Most fermented dairy drinks on the market contain generic probiotic cultures that can vary between batches. Bio-K+ is formulated with three patented, clinically studied strains — L. acidophilus CL1285®, L. casei LBC80R®, and L. rhamnosus CLR2® — co-fermented for synergy and standardized to deliver 50 billion CFU per bottle, guaranteed until best before date (not manufacturing date). This formula is backed by 30+ years of research, 16 published clinical trials, and 45+ peer-reviewed publications.

Bio-K+ Dairy Drinkable Probiotics and traditional kefir are both fermented dairy beverages, but they differ in several important ways. Kefir is typically produced using a naturally occurring blend of bacteria and yeasts; its live bacteria content and strain composition can vary significantly between brands and batches. Bio-K+ is formulated with three specific, patented strains — L. acidophilus CL1285®, L. casei LBC80R®, and L. rhamnosus CLR2® — co-fermented for consistency and standardized to deliver 50 billion CFU per bottle until the best before date. Unlike traditional kefir, Bio-K+ drinkable dairy probiotics are formulated to contribute to intestinal flora health as part of a healthy lifestyle.

Each 98 g bottle of Bio-K+ Dairy Drinkable Probiotic contains 50 billion CFU (colony-forming units) of live and active probiotic bacteria. Crucially, this potency is guaranteed until the best before date printed on each bottle — not from the manufacturing date. Many probiotic products measure CFU at the time of production, meaning potency can decline significantly by the time the product reaches store shelves. Bio-K+ guarantees 50 billion CFU across the full shelf life of the product, so you can trust that what's on the label accurately reflects what you're consuming.

Bio-K+ dairy drinkable probiotics are made with skim milk powder and whey protein concentrate and do contain dairy. They are certified gluten-free but are not lactose-free. If you have lactose sensitivity, the fermentation process does reduce, but does not eliminate, lactose content. Those with a confirmed dairy allergy should consider the vegan drinkable probiotic line instead. If you are uncertain, consult a healthcare professional before use.

Bio-K+ dairy drinkable probiotics must be kept refrigerated at all times to maintain their bacterial count, which is guaranteed until the best-before date. Once opened, keep the bottle properly closed and consume within 7 days. The product can be kept out of the fridge for up to 24 hours. After that, potency can no longer be guaranteed, and the taste will become more tart. Do not freeze.

Each 98 g bottle of Bio-K+ dairy drinkable probiotic contains 50 billion live and active bacteria from three exclusive strains. This count is guaranteed until the best-before date, provided the product is kept refrigerated. Unlike many probiotic products that declare their count at the time of manufacture, Bio-K+ guarantees bacterial potency at the time of consumption when properly refrigerated.

Bio-Kidz is a suitable probiotic for 2-year-olds and above. One bottle daily provides 12.5 billion live and active bacteria from Bio-K+'s three clinically studied proprietary strains, plus Vitamin D3 (made with vitamin D fortified skim milk powder). As with any new addition to your child's routine, start gradually and monitor their well-being. If your child has a specific health condition or is immunocompromised, consult their healthcare provider before introducing a probiotic.

Yes. Bio-Kidz refrigeration requirements are like all Bio-K+ drinkable probiotics; it must be kept refrigerated. The bacterial count is guaranteed until the best-before date when stored properly in the fridge. Once opened, the bottle can be kept refrigerated for up to 7 days with the cap properly closed. Bio-Kidz can be kept out of the fridge for up to 24 hours; after that, the taste and texture may change, and bacterial potency can no longer be guaranteed.
